To quickly assess the difficulty of the text, read a short excerpt:
The interrhopalial tentacles have totally disappeared. The lines of adhesion separating the radial canals are faintly visible as radiating lines of greater transparency. The four lips of the mouth are spread out into a cross -shaped figure and one may look directly through the lumen of the oesophagus into the stomach, and see four gas- tric filaments. Fig. 21. Each one of the four lips is nearly square and from its two outer angles there are two grooves that extend obliquely inward until they m...eet and form a V. The point of the V. Is in an ar^le of the oesophagus along which there is a groove that is continuous with these other two grooves and extends into the stomach. On the interradial side of each of the eight labial grooves there may be seen a snail roughly circular area that is less transparent than the rest. Tliese areas are the nettle batteries first seen in earlier stages. The margins of the lips are provided with numerous small processes, the digitella. These are arranged in a single continuous se- ries.
